@Paul-BOREL : Checking your previous posts, I see your system had many strange issues. Even the error when displaying IP address you posted here (I must make a patch to silently fallback to make it work on your system).
Laragon 4.0 is more flexible than previous versions. It needs to download package from the trusted sources on Internet but I believe lack of privileges on your system prevents Laragon 4.0 to function correctly.

Thanks for continuing to make improvements to Laragon. To upgrade from a previous version do we simply install the new one on top of the old one? If we do experience problems what is the correct was to roll back to a previous version? Can I take a backup before I begin and restore that?

@Dustin : Laragon 4.0 is fully compatible with Laragon 3.0. We have a major release of Laragon because Laragon 4.0 will not bundle with git, node.js by default. You can add them easily using Quick add if you need.
